MacSpeech Scribe is speech recognition software for Mac OS X designed specifically for transcription of recorded voice dictation.
MacSpeech Scribe supports specific audio file formats for recorded dictation: .aif, .aiff, .wav, .mp4, .m4a, and .m4v.
The product is now owned by Nuance Communications which acquired MacSpeech on February 16, 2010.
Jeffery Battersby of Macworld noted in his September 2010 review [1] of MacSpeech Scribe, v1.1: Small foibles aside, MacSpeech Scribe is a powerful and intelligent tool for transcribing your recorded speech.
A simple training process and access to a wide variety of standard audio formats mean that you’ll be moving your spoken text to the printed page in a matter of minutes and with a minimum of hassle.
